Abstract
An information handling system monitors current at plural current sensors during each of plural predefined events, such as power up and boot, to detect power anomalies that indicate failing components, such as bad charger, bad power rail, bad motherboard and/or back cover deck. Current during a boot event is compared to a baseline value for the event, such as a value measure and stored at manufacture of the system, and/or an average of current measured for a predetermined number of previous events. In one embodiment, a separate analysis is performed based upon whether the system boots from battery power or external alternating current adapter power.
